Abstract
Operation of a water softener is controlled by a set of valves within a body that has water inlet, water outlet, a regenerant connector and a drain outlet. Openings are provided in an exterior wall of the body through which a plurality of valve elements are received. The body has opposing exterior side walls through which a seam diagonally extends, thereby separating the body into two parts sealed together at that seam. The diagonal seam divides internal fluid chambers between each part and facilitates molding the parts so that the entire body can be fabricated by only two parts.
Claims20
A valve body, for a water treatment apparatus, comprising:
- a plurality of external connectors comprising an untreated water inlet, a treated water outlet, a drain outlet, and a regenerant connector;
- a first part formed by a single piece of material and having a fluid fitting for connection to a water treatment vessel;
- and
- a second part by another single piece of material and sealingly joined to the first part, wherein the first part and the second part substantially entirely form a plurality of internal fluid chambers a plurality of internal fluid chambers;
- wherein the plurality of internal fluid chambers comprises an inlet chamber into which the untreated water inlet opens, an outlet chamber into which the treated water outlet opens, a rinse chamber, backwash chamber, drain chamber into which the drain outlet opens, and a regenerant chamber into which the regenerant connector opens.

A valve body, for a water treatment apparatus, consisting essentially of:
- a first part;
- and
- a second part sealingly joined to the first part to form a plurality of internal fluid chambers;
- wherein the valve body, formed by the first part and the second part, includes a primary exterior wall and a secondary exterior wall, and has a first exterior side wall, and a second exterior side wall both of which extend between the primary exterior wall and the secondary exterior wall, the valve body further comprising a plurality of openings for an inlet valve element, an outlet valve element, a rinse valve element, a backwash valve element and a regenerant valve element for controlling flow of fluid through the valve body, and further includes a fluid fitting for connection to a water treatment vessel;
- the first part comprises the secondary exterior wall and a section of each of the first and second exterior side walls, and further includes an untreated water inlet, a treated water outlet, a drain outlet, and a regenerant connector;
- and
- the second part comprises the primary exterior wall and another section of each of the first and second exterior side walls.

A valve body, for a water treatment apparatus, comprising:
- a primary exterior wall and a secondary exterior wall, between which extend a first exterior side wall, a second exterior side wall and a third exterior side wall;
- a fluid fitting for connection to a water treatment vessel;
- the valve body having a seam which extends through the first exterior side wall and the second exterior side wall at acute angles to the third exterior side wall, thereby separating the valve body into a first part and a second part which abut each other to form a plurality of internal fluid passages;
- the first part contains the secondary exterior wall that has an untreated water inlet, a treated water outlet, a drain outlet, and a regenerant connector;
- and
- the second part comprises the primary exterior wall through which extend a plurality of openings for receiving an inlet valve element, an outlet valve element, a rinse valve element, a backwash valve element and a regenerant valve element.
